Notes:

1. These values apply for all valid processor bus and L3 bus ratios. The values do not include I/O supply power (OVDD

and GVDD) or PLL supply power (AVDD). OVDD and GVDD power is system dependent, but is typically < 5% of VDD

power. Worst case power consumption for AVDD < 3 mW.

2. Maximum power is measured at nominal VDD while running an entirely cache-resident, contrived sequence of

instructions which keep the execution units, with or without AltiVec, maximally busy.

3. Typical power is an average value measured at nominal VDD in a system while running a typical code sequence.

4. Doze mode is not a user-definable state; it is an intermediate state between full-power and either nap or sleep mode.

As a result, power consumption for this mode is not tested.
